Question 8

Grade Calculator (4mins)

Using functions, nested loops and type casting, write a program that takes the marks of students in multiple subjects and prints a formatted grade report.

a. Input the number of students and subjects.
b. Input each student’s marks (space-separated, one line per student).
c. Use a function to calculate the average of each student.
d. Print:
* Student number
* Their marks
* Their average (rounded to 2 decimal places)
* “Pass” if average ≥ 40, otherwise “Fail”
